Merv 11 furnace filters and AC filters can remove mold spores, pollen, dust, lint, pet dander and more. Pleated furnace filters and pleated AC filters will clean your home's air more effectively than low cost fiberglass air filters. Pleated home air filters are made from a synthetic media which can filter out much smaller particles from the air such as dust mites, mold, pet dander and even viruses in the case of high Merv rated filters. Indoor air quality has been named as one of the top 5 environmental health risks by the FDA because of pollutants such household cleaning products, mold, smoke and more. Change your home's HVAC filters regularly to ensure your home's air is clean year-round.

APR vs MERV

APR

APR stands for Accumulair Performance Rating. This rating has been established by the manufacturer of the Accumulair Filters. This rating exists to demonstrate the different levels of efficiency throughout the Accumulair filter line. Generally speaking, the higher the APR, the better the filter performs in capturing small airborne particles. This rating system is an internal rating system and applies to Accumulair filters only.

MERV

MERV stands for Minimum Efficiency Reporting Value. It is a number from a test method designed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). The number is intended to help people compare filters. Generally speaking, a higher MERV rating indicates better filter performance.
